How to quiet an EFIed 20V?

[laraa at sympatico.ca]

Hi everyone,

I drove today the 20V 034-EFIed urQ of my good friend Eric. While it is
indeed very fast, as in spinning the front tires on second gear, the intake
noise is way too loud. Each movement of the throttle that produce boost
produce also that dreaded intake noise. I mean, anything from the tiniest
acceleration to wide open throttle produce the noise. Only while cruising it
is bearable. 

The setup is a cone filter bolted directly to the turbo inlet where the
stock airbox was. I'm quite sure one can create a custom enclosure there to
encapsulate the cone filter, but is there another solution ? 

Any insight welcome.
